Introduction
The T4 is the first and smallest of a new line of tunnel-type Coded Wire Tag (CWT)
detectors. It maintains the high sensitivity of the earlier R-Series detectors and their
ability to detect a tag in any orientation while improving upon the water resistance and
general ruggedness of those units. The T4 can operate as a stand-alone detector, with a
diverter gate, or as a Quality Control Device (QCD) for a MKIV tag injector.
T-Series detectors are designed to plug together with one or more other system
components such as a beeper box, power supply, control box, and an automatic diverter
gate using a new unified system connector. Most components have two identical 8-pin
connectors with universal cables to interconnect them.
The T4 detector’s tunnel is octagonal and is 2 1/4 inches (5.7cm) by 3 7/8 inches (9.8
cm). It may be used with either the broad or the narrow dimension upright, however the
NMT (Northwest Marine Technology) funnel and gate are designed for attaching to the
detector when the larger dimension is vertical.
The T4 stand-alone tag detector functions with an audible beeper (beeper box). The
beeper box has a power ON light and will beep and light two red LEDs when a tag is
detected.
For diverting fish, the T4 is supplied with a diverting gate and a control box. The control
box controls the settings for the gate, detector and control box functions and records
counts of detected tags in up to four different groups. Using the control box it is possible
to adjust the system for a variety of situations, such as fish that move unusually fast or
unusually slow.
When used as a Quality Control Device (QCD), the T4 detector uses the diverting gate
and a special interface box which connects to the MKIV tag injector. The MKIV controls
the gate and detector.
The T4 detector may be powered from the NMT 24VDC power supply which has an
input AC voltage range from 100-250V, from an 18VDC rechargeable battery supplied
by NMT. If you wish to operate the T4 detector and accessories from a different 24VDC
power supply than please contact NMT for more information.
The T4 is equipped with a folding set of legs as well as a watered fish funnel.
A detection standard (a dowel with a standard length coded wire tag embedded in one
end and a 1/2 length l tag in the other) is supplied with each detector. This is used for
verifying that the detector is working correctly and for determining the correct settings on
the control box.

Legs
The aluminum legs are telescoping and sturdy. They fold into a compact unit for
transport or storage. There are rings on the leg stand for attaching a sling which keeps
the battery or power supply away from water and off of the ground.
Set the folded legs down so that the long legs and sling are facing up (the leg label will
be down). Loosen the side knobs on all four legs. Pull the long legs up, then the shorter
legs. Loosen the leg clamp and pull the back, shorter legs all the way out and push them
back against the edge of the leg stand, tighten the lever and the 4 prong knob. After the
back legs are adjusted adjust the height and angle of the front legs.
Turn legs over and adjust the height and angle of the legs to suit the ground surface.
The height and angle of the legs can be adjusted to increase or decrease the speed of
the fish through the tunnel.

The detector may be attached to the leg stand with the fish tunnel in either the vertical or
horizontal direction. If using the fish funnel, or diverter gate, the detector tunnel must be
in the vertical direction. The leg latches on the front end panel and the leg alignment
blocks on the rear panel are mounted so that the tunnel is in the vertical direction. If you
want the tunnel in the horizontal direction, then the alignment blocks and the latch bar
with latches will have to be moved to the side of the end panel so that the connectors on
the rear panel will be at the top.
The T4 detector should be set up away from equipment that generates strong magnetic
fields such as large motors because these magnetic fields may cause false positive
detections. If this happens, move the detector further away from the source of the
magnetic field.
Fish Funnel
The fish funnel attaches to the front panel of the detector and helps guide fish into the
tunnel. It also provides a way to inject water to help lubricate the tunnel. The water
source can be an ordinary garden hose connected to the hose fitting at the bottom of the
funnel support structure. The flow valve above the hose fitting can be used to regulate
the water flow. When the valve is properly adjusted, streams of water will emerge from
vents at the top edge of the funnel.

Near the bottom of the funnel bracket are two locating pins that fit into two holes on the
lower front panel of the detector. Set the bottom of the funnel into the bottom of the
aluminum fish tunnel; slide the pins into the holes.
You may need to gently squeeze the sides of the neck of the fish funnel to get it to go
into the aluminum fish tunnel. The bottom half of the neck of the funnel must fit inside of
the entrance to the detector tunnel; the top half is designed to line up with the tunnel
entrance, but remain just outside.
Make sure that the clips on the top and bottom edges of the funnel are out of the way
when positioning the funnel, and once the funnel is in place, close the clips over the
edges of the detector end panel.

The clips should move easily, do not force them closed. Check that the bottom edge
and lower sides of the plastic fish funnel are inside of tunnel before tightening clips.
Be sure the locating pins on the funnel bracket are properly inserted into the holes in
the front panel.
Attach a hose to the fish funnel as for the stand alone detector. Adjust the water flow so
that the fish are sliding easily through the tunnel. The water coming out of the back of
the detector should be hitting the ground at about 12 inches from the end of the tunnel. If
the water flow is not adequate then the fish will go too slowly through the detector and a
single tag may be detected twice. For starting, set the leg heights so that the top edge of
the funnel is parallel to the ground.

Connectors and Plugs
On any unit in the T4 system, the two 8-pin connectors are identical. The universal
cables are all the same with the two ends being identical, so it doesn’t matter which
cable gets attached to which connector..
It is important, however that units are hooked together in a chain.
To make sure of good electrical contact and waterproof assembly, the plug connectors
on the universal cables require a three step connecting process when inserted into a
panel connector. First rotate the plug in the connector while pushing very gently until you
feel the plug fit on the connector pins. Push the plug into the 8-pin connector as far as it
easily goes. Now turn the locking ring at least a half turn while continuing to push:
usually the plug will slide in a small additional amount. Finally turn the locking ring
clockwise until it comes up snug.
If an 8-pin system connector is not in use then the dust cover should be closed over it for
protection against dirt and water.

To connect power to the detector, set the 24V power supply or the battery supply in the
sling.
The power supplies must be kept out of the water.
If you are using the 24V power supply, plug the cable with the 8 socket plug into the
eight pin connector on the back of the detector, gate or control box. Plug the cable with
the three prong connector into a wall outlet or an extension cord.
If you are using the 18VDC battery, be sure the battery is fully charged. It is best to
charge the battery for a full 8 hours before each use to have it work at maximum
capacity. See instructions supplied with the battery charger for further information. Plug
one end of a universal cable to the 8 pin connector on the battery face, and attach the
other end to a free connector on the detector, gate or control box.
Slide the on/off switch up to the on position; the green Power ON Led should light up.
The slide switch is on the back. If the battery is low, the red Low Battery LED will come
on. Always change or charge the battery as soon as the red Low Power LED comes on.
With just the detector and beeper box, a fully charged battery should last 30 hours. As
the battery gets old, or if not properly charged, this may be less.
The combination of detector, gate, and control box will run for approximately 4 hours on
a fully charged 18V battery. The time may be more or less depending on the age of the
battery and how it was charged. If you are taking the detector to the field, a second
charged battery is essential.
CAUTION: Change the battery as soon as the red LOW Battery LED comes on.
From the time the red LED lights until the battery is completely dead takes
approximately 7 minutes when using with the detector, gate and control box. The
gate will stop functioning before the battery is completely dead, the beeper on the
control box will continue to work for a few minutes, and finally the display will flash
and then go blank.

Detection Standard
The detection standard is a wooden stick which has a standard length CWT imbedded in
one end and a 1/2 length tag imbedded in the other end. A single ring around the end of
the stick indicates the end with a 1/2 length tag and the end with two rings indicates the
standard tag. Pass the detection standard through the tunnel to verify that the detector is
detecting tags and to determine the range of speeds at which a tag is detected.

Gate
The gate opens when a CWT is detected, allowing separation of tagged from untagged
fish. Its time of opening and closing can be adjusted to accommodate fish of different
lengths, moving at different speeds, and being fed through the tunnel at different rates.
Mounted on the top of the gate is a box that holds the electronics. On the side of the box
is a button switch which activates the gate flapper for clearing jams.
The 5 digit serial number, beginning with 43 is on the back above the connectors.
The gate settings are edited from menus in the control box (refer to Equipment

Connecting Units Together
Depending on whether you are using the 24V power supply or the 18V battery supply,
you will need either 2 or 3 universal cables to attach the T4 detector/diverter gate/control
box/power system together.
If you use the 24V power supply plug its 8 socket plug into one of the gate connectors.
Plug one end of a universal cable into the other gate connector and plug the other end
into a connector on the detector. Take the second cable and plug one end into the free
connector on the detector and plug the other end into one of the free connectors on the
back of the control box. You may change the order of the cables so long as all of the
units are interconnected.
If you use the 18V battery supply, then three universal cables are used.

T4 Detector and Gate as a QCD
MKIV Interface Box
The T4 detector and gate may be used as a QCD (quality control device) with a MKIV
tag injector. When operating in this mode the gate and detector are controlled by the
MKIV through a special interface box. Neither the control box nor beeper box is used
during the operation with the MKIV. A control box is needed, however, to verify that on
the gate setup menu that the mode is set to “wire”. This is the setting set at the factory,
but might inadvertently get changed by someone going through menus on the control
box. Once it is determined that the mode is set to “wire” then the control box is
disconnected or removed.
The interface box has two system connectors and a cable with a 16 socket plug that
attaches to the MKIV. One universal cable is attached between the MKIV interface box
and the gate, and another is attached between the detector and the MKIV Interface Box.
Figure 1- 22: T4/MKIV Interface box.
Two 8 pin system connectors that
attach to gate and detector, order

16 socket plug attaches to MKIV
The MKIV injector can use the T4 detector as a quality control device in place of the
QCD. When properly attached, all settings for the detector and gate are made from the
MKIV as they would be with the QCD.
The T4 detector is set up on legs with a funnel and gate as already described. The T4
detector and gate will be powered through the gate with either the 24V power supply or
the 18V battery supply. If possible use the 24V power supply. The battery life of the 18V
battery is approximately four hours but may vary depending on the age of the battery
and the charge.
The MKIV is powered from its own power supply. Please consult the MKIV user’s
manual for instructions on using the MKIV.

This is the one situation in which it does matter how the power is attached to the T4
detector and gate. Whenever the T4 and gate are used as a QCD with the MKIV, the
power for the gate/detector must be plugged into one of the gate connectors and not into
the detector.
If the gate has been used with a control box then you must verify the gate setup
menu setting for Mode. It must be set to “wire” for the MKIV to work with the gate
and detector. Please refer to the Gate basic menu and to the T4 Detector and
Gate as a QCD in the Equipment Operations section.
The gate is shipped from the factory with Mode set to “wire”.

2. Equipment Operation
T4 Stand-Alone Detector Operation
The stand-alone detector configuration has a beeper box.
Attach the detector to the legs and the beeper box, fish funnel, and power to the
detector. (See: Equipment Description and Setup.) Once you have power to the
detector, hook up a garden hose to the hose connector on the fish funnel. Adjust the
water flow with the black handled valve. Water will come out around the upper front
edges of the funnel. For starting, set the leg heights so that the top edge of the funnel is
parallel to the ground. If you do not have a steep enough angle on the detector or if the
water flow is not adequate then you may get a double detection when a fish is moving
too slowly.
On the stand alone T4 detector, the fish speed and the gain (sensitivity to the tag) are
set at the factory. If the tag goes through the tunnel at too slow a speed, it may be
detected twice. If this should occur, increase the speed that fish are going through the
tunnel.
Once power is connected to the detector it takes about 20 seconds before the
detector will detect a tag and sound the beeper.
Tag detection
Once everything is hooked up, pass the detection standard through the tunnel several
times to determine that tags are being detected. Move the tag through at the rate you
think your tagged specimens will be going to verify that the detector will detect a tag at
that speed. Confirm this speed by putting some test fish through the detector. Be sure
the water is on and adjust the leg angle until the fish pass through at a rate such that the
beeper always goes off when a tagged fish goes through the center of the tunnel.

T4 Detector, Gate and Control Box
Operation
Follow the instructions in the Equipment Description and Setup section to get your
system ready for operation. The detector will be attached to the legs. The gate, funnel
and control box will be attached to the detector. Connect all cables and power. Establish
water flow through the detector as described in the section on the funnel.
T4 Detector
The T4 detector is connected by cables to the power, the gate, and the control box. The
menu for tag detector will be visible on the control box display when the detector is
getting power. Once power is connected, it takes about 20 seconds for the detector to
warm up. The way to know that the detector is getting power is to see if the menu for the
tag detector is visible on the control box display.
Gate
When the gate is receiving power it will make a hissing sound. Push the button on the
side of the gate electronics box and the flapper will go back and forth.
Control Box
When the control box is receiving power the green LED will be lit, and the Tag Detector
menu will be visible on the display. The control box displays the menus for the
equipment in the system, in this case the detector, gate and control box. The control box
can tally tag counts for up to 4 groups.
The control box beeper is very loud. In a quiet environment you may wish to cover it with
several layers of tape or insert foam ear plugs into the hole. The beeper sounds when a
tag, or other moving object that has a magnetic field, passes through the detection
range. If two closely spaced tags go through the detector, the beeper will sound for a
longer period of time.
When power is first applied to the control box the words “NMT T SYSTEM” appear
briefly on the display. If the detector, gate, and control box are all hooked up, then the
Tag Detector Operation menu appears next. If the control box is powered without being
connected to the detector, then the control box operation menu will be seen on the
display.
The detector, control box and gate each has its own set of three menus: Properties,
Operation and Setup. The Operation menu is the first menu displayed for each unit. After
setting the gain on the Tag Detector Operation menu, and the fish speed and Gate open
and close times on the Tag Detector Setup menu, you will most likely want to have the
Operation menu for the control box visible while detecting tags and recording counts.
T4 User’s Manual

Detection Standard
The ability of the T4 to detect a CWT is dependant upon the speed that the fish is
traveling through the tunnel. If the fish are moving slower than the fish speed entered in
the Tag Detector Setup menu, than the tag may be detected twice; if the fish are moving
too fast for the set fish speed, then the tag may not be detected. For this reason a
detection standard (a dowel with a standard length coded wire tag embedded in one end
and a ½ length tag in the other) is supplied with the detector. Users should move the
detection standard in and out of the tunnel at the speed the fish will be traveling in order
to get an idea of how to set the fish speed in order to get a proper detection.
The detection standard has a 1/2 length tag in one end and a standard length tag in the
other. Pass the end of detection standard with the tag length you will be using through
the tunnel to determine the best gain setting on the Tag Detector Operation menu. The
signal bar graph should be about half way to the vertical Tag Detection threshold line
when a tag is not present.
Threshold line, when bar goes above this line a
tag has been detected.
The signal bar will flicker back and
forth. Its maximum excursion should
be about half way to the threshold line
when a tag is not present.

Menus Navigation and Editing
There are a few rules for navigating and editing menus. Once learned it is very easy to
move and change values on the various menus. We recommend experimenting with a
control box that is hooked to a gate and detector while reading the rules below.
A cursor in the form of an underline is always present somewhere in the display.

Refer to “Initial Settings for T4 Tag Detector, Gate and Control Box” chart that is on top
of the detector and copied in this section as well as the “Menus on Control Box” sheet
which is also in this section.
Getting Started
On the top of the detector there is a chart “Initial Settings for T4 Tag Detector, Gate
and Control Box”. If these values are entered for each unit (and the Full menu values
have not been changed), then the system will work. Start with these settings, then fine
tune your settings to meet your specific needs.

The issues you need to think about when putting fish through the T4 detector and gate
are fish speed and fish spacing.
1. Fish speed: Fish speed can be affected by the angle of the detector and the
rate of water flow through the funnel and detector tunnel and how the fish are
entered into the funnel. Set the detector as described earlier so that the top of
the funnel is parallel to the ground. Establish a good water flow so that it hits the
ground about one foot out from where it comes out of the gate. Set the Fish
Speed on the Tag Detector menu to 1 m/s, and Gain at 48. If you put well
spaced tagged fish through the detector and there is only one detection then the
water flow is adequate. If fish get caught up or move too slowly then two counts
may occur. Either adjust the angle of the detector, water flow or set the fish
speed slower. At a fish speed on 1 m/s you will get all of your counts. If your
Fish Speed on the Tag Detector menu is set too high for the actual speed your
fish are going through the detector you may get double counts, so it is better to
set the fish speed lower and have your fish move faster. However, if your fish
speed is set too low and you have fast moving fish, then the tag may not be
detected.
2. Fish spacing: It is important that one fish is through the detection region of the
detector before the next fish enters the detection region. If the Gate Open is set
at “0”, the gate will begin to open as soon as the detector registers a tag. The
length of time the gate stays open is determined by the Gate Close time. If the
gate opens too soon or stays open too long then a fish may be misdiverted.
Using the suggested settings put fish through the detector and watch that they
get through the gate with plenty of clearance. Look down the tunnel as you feed
fish into the funnel and see how they clear the flapper. If you feed fish into the
funnel quickly, you may need to shorten the Gate Close time from .5 sec to .3 or
.4 sec.

Basic and Full Menus
For most applications the menus on the control box may be set up as described on the
“Initial Settings for T4 Tag Detector, Gate and Control Box” chart. Minor adjustment in
gain, fish speed and gate timing may be required.
This section is a more detailed explanation of the various menus, definitions of terms
and applications and navigation between units and menus.
For reference refer to the table on the next page titled “Menus on Control Box”. Green
represents the Tag Detector, orange is the Gate and purple is the control box. Each unit
has three menus, and moving between the menus is represented with the blue arrow
(white for moving in control box menu between the count Groups 1,2,3,4).
The suggested settings for each unit are listed under Default; other possible settings are
listed under “Alternate”
If you look at the table “Menus on Control Box”, you will see that most menus are in
black, but a few lines are in purple. All of the black represents the basic menu. If the
menu style is set to basic then only those items in black will be visible on the display. If
the menu style is set to full, then everything in black as well as purple is visible on the
display. The full menu is only needed when you have more than one detector, gate, or
control box hooked together. However, the settings in the full menu can affect how the
equipment works, even if you are operating only a single unit, the settings on the full
menu should be left at the defaults shown in the table “Menus on Control Box” unless
you are instructed to do otherwise.
Do not change the Full Menu settings unless instructed to do so.
The Basic Menus for all units will be discussed first and then the Full menus.

Basic Tag Detector Menus
When the Tag Detector menu appears, there is a number to the right on the same line
as the words “Tag Detector”. The number is the unit ID (identification) number, in this
case <Tag Detector 1>; both the caption and the number “1” are underlined in a
continuous line, so the unit ID number may not be changed from this menu. The factory
setting is 1. <Tag Detector 1> is at the top line in all three of the tag detector menus.
On the second line of the display, the cursor can be scrolled left or right between the
three tag detector menus: Operation, Properties and Setup.
1. <Operation>: When the Tag Detector Operation menu appears there is a solid
line across the display under <Operation>. The “<>” arrows indicate that you
can scroll left or right from the <Operation> menu to either the <Properties> or
the <Setup> menu.
a. Signal Bar Graph, Gain: With the solid line under <Operation>,scroll
down one line so that the solid line moves under the bar graph across the
display. This is a visual setting for “Gain”. The “Gain” is the setting for the
tag detector’s sensitivity to magnetic disturbance. The detectors are
designed to exclude all magnetic fields except those created by an object
going through the detector. However, some stray magnetic fields do get
into the detector and this is referred to as background noise. The
fluctuating bar on the left is the magnetic noise at the numerical gain
setting indicated on the next line down. The vertical line in the center
marks the detection “Threshold”. When the magnetic disturbance is large
enough, the bar goes above threshold and the detector beeps.
i. The bar graph is the one exception when a cursor under the entire
line allows editing. The gain value may be changed by either
changing the length of the bar or by changing the numerical value
in the line below. To edit gain from the bar graph, push the right
button to increase the gain or the left button to decrease it. You
will see the numerical value will change with each push of the
button, and the length of the bar will either increase or decrease.
ii. Set the gain so that the background noise, or bar, is between 1/3
and ½ way to the threshold mark. In a fairly quiet environment this
is at about 48. Verify the setting using the detection standard.
b. Gain, Number: Push the down button again, now only the displayed
number is underlined. The length of the line is three digits. To edit this
value, push either the right or left button; the underline will change to a
shorter line that is the width of a singe digit. Keep pressing the button until
the line is under the number you want to change. Push the up button to
increase the number, push the down button to decrease the number. If
you set the gain too high, then the bar on the graph will go above
threshold and the beeper will sound continuously. When you have the
number you want, push either the right or left button until the single digit
cursor goes off the end of the filed and broadens to an underline three
T4 User’s Manual
Equipment Operation
37
digits wide under the entire number, now you can push the upper button
and move the underline to a different part of the menu.
2. <Properties>: There is a solid line across the display under <Properties>, but
by pushing the right or left button you may scroll to a different menu,
<Operation> or <Setup>. None of the items on the Properties menu may be
changed. This is indicated by the full width underline when you scroll down to
any item. This menu gives information about this detector; all values are set at
the factory.
a. Serial Number: The serial number is unique to this detector. The serial
numbers for the T4 Tag Detector begin at 4000.
b. HW Version: This represents the Hardware version of the detector.
c. FW Version: This is the version number of the software for the
electronics in the tag detector.
3. <Setup Menu >: <Tag Detector 1> will be the top line as described under the
operations menu. With the solid underline under “Properties” push the left
button once or the right button twice and move to the Setup menu. Two of the
gate settings are on this menu since the time that the gate opens and closes is
dependant on the signal being sent from the detector to the gate.
a. Gate Open (sec): Scroll down to this line. Gate open is the elapsed time
from when the tag is detected to when the gate opens. The time value is
set on the right. For most circumstances settings to tenths of seconds is
adequate. For the gate to begin opening as soon as a tag is detected set
it to 0.00.
b. Gate Close (sec): Scroll down and edit the numbers as before. Gate
close is the time from when the gate opens until it begins to close. This is
set long enough so that the largest fish can get through before the gate
closes, but short enough so that the gate is completely closed before the
next fish has reached the front edge of the gate flapper.
c. Det. Mode: Detector Mode is the setting which determines when the tag
is registered by the detector. There are two options; Early and Precise.
i. With Early detection, the tag is detected early in the tunnel and
the signal is sent to the gate before the tag reaches the center of
the tunnel. If your fish is moving too slowly through the tunnel in
this mode, the detector will beep twice. This mode is used when
you have long fish going in tail first. The tag must be detected and
the gate opened before the tail of the fish reaches the flapper.
ii. In Precise mode the tag is detected near the center of the tunnel,
and is a short distance past center before the detection is
confirmed and a signal can be sent to the gate. In this mode, a
very fast moving fish may reach the gate before it has time to
open, but closely spaced fish moving at moderate speed can be
more readily separated. Precise is the suggested detection mode.
iii. When you scroll down to Det. Mode the entire word “Early, or
Precise” is underlined. To edit from Precise to Early, push either
the right or left button. The cursor becomes a single line under the
last letter (e); push the up button once to go to Early. Push the left
or right button again to underline the entire word; this sets the
word in memory. To go from Early to Precise, the method is the
T4 User’s Manual
Equipment Operation
38
same, except that the cursor is only under the “y” in Early (y);
push the down button to go to Precise.
4. Fish Speed (m/s): Fish speed is defined as the speed in meters per second
(m/s) with which the fish are going through the tunnel. The speed depends on
the angle of the detector and on how much water is going through the tunnel
with the fish. Scroll down to the caption Fish Speed (m/s).The cursor is under
the number at the right. This number on the first line is all that can be changed.
The “Typical 1 m/s” is for reference and is the suggested setting. The fish speed
may be set to tenths of m/s from 0.2 to 3.0 m/s, but 1 m/s is a good starting
point and will work well in most non-critical situations where the actual fish
speed is not well known or well controlled. Edit the fish speed in the manner
described above. Using the up button scroll back to the top of the menu until
“Tag Detector” is underlined. Scroll right to Gate or left to Control Box.
Basic Gate Menus
1. <Operation>: The name of the unit and its ID number <Gate 1> will be the top
line when first scrolling to the gate unit. When this menu appears the cursor is
under Operation. When the cursor is under Operation you can scroll right or left
to the gate’s <Properties> or <Setup> menu, or down to the items listed below.
a. Tagged: The value field contains either the word “left” or “right”,
indicating which side of the gate the tagged fish are diverted to. The
directions apply when looking from the front of the detector toward the
gate. This choice is set by the user.
b. Untagged: Again the value field will say either “left” or “right”. Usually if
tagged fish are set to go to the right then untagged fish would go to the
right. If you want all fish to go in same direction, but still count the tags,
you would set both the tagged and untagged to the same side.
c. Now open to: You must scroll down to this line as it is not visible when
the display first comes up. The software is set so that the untagged side
is the one that is open. Between detections, this will have a value equal to
that of “untagged”.
2. Properties Menu: Scrolling here from the operation menu the cursor will be
under <Properties>. <Gate 1> will be the top line. You can scroll from
<Properties> left or right to the <Operation> or <Setup> menu.
a. Serial Number: The serial number for Gates begins at 43000. The
number is set at the factory.
b. HW Version: Hardware version, set at factory.
c. FW Version: The version of control program for the gate.
3. Setup Menu: Scrolling here from the Properties menu the cursor will be under
<Setup>.
a. Mode: This relates to the way that the units on the system communicate
with each other. There are three choices, wire, message and test. When
there is just one gate, one detector and a single control box then use
wire, wire is also the only mode that works when the T4 detector and gate
are being used as a QCD with a Mark IV tag injector. Message is used
T4 User’s Manual
Equipment Operation
39
when there are multiple units of the same type hooked together in the
system. Test is only used at the factory for set up and repair.
Basic Control Box Menus
As with all menus, the name of the unit and its ID number is the first line, in this case,
<Control Box 1>. From that line you can move right or left to the Tag Detector or the
Gate menus.
1. <Group 1> (2,3,4): In reality these are four operation menus, but due to limited
space the line that would say <Operation>is not present. The control box can
keep track of tag counts for 4 different groups of fish. Each group can be
accessed by either pushing the appropriate LED button at the bottom of the
control box or by scrolling through the Groups with the right navigation button.
After group 4 you have completed going through the operations menus, and you
will go to the Setup menu; and if you scroll right again you will be at the
properties menu. Note that if the light is on in Group 1, but you scroll to Group 2,
you are still counting in Group 1 and viewing the information for Group 2.The
menus and editing for each count group is the same, so it will only be discussed
for Group 1. In each group menu there are the following:
a. Tag Count: The editable value field of this line represents the number of
tags that have been counted for this group of fish. An easy way to clear
the count to “0” is to push and hold the right and left buttons at the same
time. Edit the number works as before; push the right or left button until
the cursor is under the number you want to change and then push the up
or down button to increase or decrease the count. Push the right or left
button to get the cursor under the entire number and then scroll down.
b. Fish Count: At this time fish count is not available (N/A). In the future we
hope to have a fish counter that can be attached to the system to count
the total number of fish that have gone through the detector.
c. Edit Name: This line is below Fish Count, and is normally not visible, but
you can scroll down to it. By entering a name in this line’s value field, you
change the corresponding field of the Group caption line, so you can label
each group with your own choice of group name.
i. Editing the alphanumeric field works much like editing a numberyou use left-right keys to select a digit position and up-down keys
to alter it. The difference here is that the choices include not only
numerals but also capital and small letters. The up key steps
through the capital letters A-Z, then the small letters a-z, then the
digits 0-9. The down key steps through the sequence the other
way. Choosing each letter in turn you can build up a group name
of up to ten characters, such as “Male Coho”. When done, step
the cursor off one edge of the field to get the cursor below the
whole name, and then step up or down to another line.
ii. To delete a name, go to the edit name line and press the right and
left buttons simultaneously.
iii. Scroll using the right button through groups 2,3,4 to <Setup>.
2. Setup Menu: From <Setup> you can scroll right or left to Properties menu or
Group 4 menu.

a. *Clear All Counts*: Move the cursor to this line. By pressing the right
and left buttons simultaneously the counts are cleared in all four of the
groups at the same time, keep holding the buttons until “OK” appears.
Release.
b. Count In Group: This is another way of setting the group you want to
count in. You can select the group from the LED buttons at the bottom of
the control box or you can edit this number to the group you want to count
in. If you change the group with the button at the bottom you will see the
number change here. If you want to use the tunnel as a detector only and
not count in any group you may set the count group to “0”, and no counts
will be recorded.
c. Beeper: Scroll down to beeper. There are two choices, ON and OFF.
The beeper should be ON unless you have a specific reason for it to be
off. Without the beeper your only signs that a tag has been detected are if
the red LED on the front of the control box lights up; if you are viewing the
Tag Detector operations menu, the bar will go above threshold, or if you
are looking at the counts in a selected count group the tag count will
increase.
d. Menu Style: This should be set at basic unless you are told to do
otherwise. To change to Full, push the right button so that the line is
under the “c”, push the up button. To change back to Basic push the
lower button. To set, push the right or left button until the word is fully
underlined.
e. Fish Counts: This is here in anticipation of a unit that will count total
number of fish that go through the detector. N/A means that this unit is
not available. If such a unit becomes available, then the N/A would be
switched to Show, and the fish count would show on the Group menu.
i. Scroll back up to the <Setup> line and push the right button.
3. Properties Menu: From <Properties> you can scroll right to <Group 1>, or left
to <Setup>. As with the other units, the properties menu is informational. All of
the values except for Voltage are set at the factory.
a. Serial Number: the serial number for Control Boxes begins at 46000.
b. HW Version: Hardware version, set at factory.
c. FW Version: Firmware version, set at factory
d. Supply (Volts): This reads the voltage of the power supply or the
battery, whichever is being used. This is a good place to check battery
voltage to see if it needs charging. When the cursor is here, it will flicker
as the voltage changes and is updated.
Full Menus
Full menu items are in purple in the “Menus on Control Box” table. They are only visible

2. Setup menu:
a. ID of this unit Tag Det 1. This is where the ID number that you see at
the top of the Tag Detector menus is set. If another detector were
attached to the system, this line would be used to set its ID number to 2
so that the two units could be distinguished. It is possible, from the same
Control Box to view the menus of two or more detectors hooked up
together, but only after the unit numbers have been set to be distinct. As
a result, the address of one must be changed before the second one is
connected. If two indistinguishable units are connected, the control box
will complain when asked to access either one of them.
Full menus Gate
1. Properties menu:
a. Action Time (msec). This is the action time of the gate in milliseconds.
It is the time that elapses between the signal to open or close the gate
and the completion of that motion. This value is set at the factory and is
usually 60 msec, but it may vary.
2. Setup Menu:
a. ID of this unit Gate 1: This is the ID for this gate, normally set to 1. If
you are using two detectors and two gates, then the ID of the gates and
detectors must be set to distinct values before connecting multiple units of
the same kind to the same control box.
b. Input to Gate Tag Det ID 0: With only one detector in the system, and
with the Tag Detector ID as 1, then this number can be either 1 or 0. The
advantage of 0 is that it recognizes any detector that is hooked up,
however if you have more than one detector and gate assembly hooked
up to a single control box and you want to look at a particular
gate/detector combo, you must have the ID of the detector correctly
matched to the gate it is to control.
Full menus Control Box
1. Setup menu:
a. Menu Style: There are two options Basic and Full. Normally the choice
is Basic, but as described in this section there are occasions when the
Full menu is required.
b. ID of this unit Control Box 1: As with the other units, if there is more
than one control box hooked into a system, then each must have its own
ID number. When there is only one control box its ID number would be
1.
c. View: There are two options, Normal and Subnet. For most purposes
you would use Normal. In this view as you scroll from one unit to another
in the system you go from tag detector to gate to control box. If you have
two tag detectors and gates, then you would scroll through tag detector
1, gate 1, control box 1 then tag detector 2, gate 2, control box 2 etc. If
you want to see the tag detectors grouped together choose Subnet, then
you would scroll tag detector 1, tag detector 2; gate 1, gate 2, then
control box 1, control box 2.

d. Inputs to counter: These are the units that are hooked up in the
system that relay active information to the counter.
I. Tag Det ID: If this is set at “0” then all tag detector signals
from all detectors hooked up in the system will be counted. If
it has a number other than ‘0’ then only a detector with that
particular ID number will have its tag counts registered on
the counter in the control box.
II. Fish Det ID: At present there is no fish detector, but when
there is, it will work like the tag detector. If a “0” is chosen
then all fish passing through all fish counters would be
counted, otherwise only fish passing through the fish
detector with the given ID number would be counted.
III. Switch ID: This is designed to accommodate a foot switch
for moving between count groups. It would operate much as
the lighted buttons do. AT present a foot switch is not
available.

T4 Detector and Gate as a QCD,
Operation
Using a control box check the gate setup menu and verify that Mode is set to “wire”. This
is the suggested setting and the setting that is in the gate when shipped from NMT. The
MKIV tag injector will not work with the gate and detector if the gate mode is not set to
“wire”. Once the mode is set then all other settings are made from the injector, and all
counts are read from the MKIV display.
Refer to the Equipment Description and Setup section for the setup of the gate and
detector with the MKIV tag injector.
Once the units are hooked together, then all operation is done from the MKIV. Please
refer to the MKIV user’s manual for complete instructions on how the MKIV works.
Testing MKIV with the T4 Detector
Remember: The T4 is replacing the QCD, so whenever the MKIV display says
”QCD”, it applies to the T4.
1. Connect a domestic 15V NMT power supply with an amp connector to the MKIV.
2. Connect the 24V international power supply to the T4 gate.
3. Connect a T4 cable between the gate and the MKIV interface box.
4. Connect a T4 cable between the detector and the MKIV interface box.
5. Plug the power supplies into a wall outlet.
6. The gate will be hissing when it is on.
7. Pass a tag through the detector to verify that it has power and is detecting tags.
8. Push the ON switch on the MKIV.
9. The display should read Ready VXX
10. If the connection between the MKIV and the detector is not good, then a
message NO QCD will appear. Remember that the T4 is acting in place of a
QCD. Check cable hook ups.
11. Press BATCH. Counts for the QCD will appear (press twice). Run a tag through
and verify that the count changes. Clear counts when done by pressing CLR.
12. For checking gate delay: Press ADJ, scroll with the +1, -1 through the menu.
When you get to QCD DELAY (50); press OK, the brackets are removed and
you can edit value. Use the -10, +10 -1, and+1 keys to adjust value. I suggest
going to 20 so that you can see and hear the difference in length of time that the
gate stays open when a tag is detected. Press OK and the brackets will
reappear.
13. Press SHOW, and then press TAG . The MKIV sends a tag signal and the gate
will open and the MKIV will count an injection cycle. Verify that the gate open
time is shorter. If so then the MKIV and T4 are talking correctly.
14. Press ESC, then press ADJ and set the QCD DELAY back to (50).
T4 User’s Manual
Equipment Operation

15. For checking QCD threshold (gain): Press ADJ and scroll to QCD
THRESHOLD. The default for Standard tags is 50; the default for 1/2 length tags
is 20.
16. Tag credit is the number of fish allowed without a tag before an error beep is
heard. This number is adjustable, but is sent out at 2. In order to test this, the
MKIV must have wire (See below). Press the TAG button three times. The third
time it should beep. Run a tag through the detector and it will reset and then
press TAG another three times to verify.
Putting Wire into MKIV
1. Put spool onto sprocket so that wire goes over the top and around the back.
2. Engage drive rollers.
3. Push wire forward until it touches drive roller.
4. Press LOAD.
5. Turn drive roller until wire sticks out end of needle.
6. Press OK. (an extra long tag will be cut).
7. Press TAG several times (MKIV will beep if have passed the Tag Credit number).
Shutting Down MKIV
1. A tag is left in the cutter and must be removed. Press LOAD.
2. Run the wire forward until it sticks out of the needle by turning the drive roller and
wipe off the cut tag.
3. Run wire back out of the drive rollers.
4. Disengage the drive rollers
5. Press ESC and display returns to READY V. #.
6. Press on/off switch to shut off power.
Mode on the gate Setup Menu must be set to “wire” for the MKIV to work with the gate
and detector.
Radio Frequency Interference
The T4 tag detector has been designed to withstand radio frequency interference from
hand held radio transmitters and cell phones kept at a moderate distance from the units.
However if a radio transmitter is operated closer than six feet (2 meters) it may set off
the detector and give false positive detections.
Magnetic Interference
The T4 detector should be set up away from equipment that generates strong magnetic
fields such as large motors because these magnetic fields may cause false positive
detections. If this happens, move the detector further away from the source of the
magnetic field.

4. Maintenance
Care of the T4 Detector, Gate and Control Box
The gate electronics, the detector electronics, and the control box are designed to be
waterproof; however care must be taken not to damage the silicone seals around the
ends of the fish tunnel
Do not drop the detector, gate or control box; internal parts could be damaged.
Charging batteries
Batteries should be charged when partially depleted. For best performance, charge for at
least 8 hours. Please refer to DeWalt manual for information about the battery charger.
Cleaning
At the end of each session, unplug the power and beeper cables from the back of the
detector and put the caps over the connectors before washing. Be sure that the
connectors are dry before closing the caps.
Remove the 24V power supply or 18V battery from the sling under the detector. Wipe
dry if they are wet. Do not spray them with a hose.
Wash the detector, gate and fish funnel thoroughly with water or soap and water. Use a
soft brush and or sponge to remove scales and fish slime. DO NOT USE A HIGH
PRESSURE HOSE. Use normal water pressure for washing the detector.
Disinfection
To disinfect the equipment we recommend using household bleach (which is a 5%
solution of sodium hypochlorite) and diluting it 1 part bleach to 25 parts water for a final
solution of 200 ppm hypochlorite and leaving it on for a minimum of 10 minutes. Rinse
the equipment well with clean fresh water after disinfection.
Disassembly
Before moving or shipping the T4 detector, unplug all cables and cover the connectors
with their dust caps. Remove all accessories from the detector. Remove the detector
from the leg stand and fold the legs. The sling is left in place.
